Data & Automation Engineering Intern

Job Description

Launch Your Tech Career with Purpose

At Reli., we're not just processing 10,000+ eCommerce orders a day - we’re reimagining how data and automation scale business in real time. As a Data and Automation Engineering Intern, you won’t be stuck in the background. You’ll be front and center, building real tools, writing real code, and solving real problems that fuel operations for our high-impact partners like Marvel, Domino’s, and Lululemon.

This isn’t your average internship. It’s a 12-week launchpad designed to give you engineering superpowers (well, close enough). Program Perks

Hybrid setup with real-life team energy (and snacks!) in Cerritos HQ

Mentorship from experienced engineers and cross-functional exposure to marketing, product, and operations teams

Dedicated feedback, learning moments, and space to grow

Opportunity for future full-time offers

You’ll work with the team on core summer project, scoped to be meaningful, buildable, and demo-worthy by the end of the program. Alongside this, you’ll:

Build Python-based tools that automate marketing, inventory, and operations workflows

Engineer smart scripts that interact with Amazon Advertising and Seller APIs

Analyze structured and unstructured data with tools like Pandas and NumPy

Collaborate with engineers, marketers, and product folks in cross-functional sprints

Present your final project to senior leaders and company-wide stakeholders

What You’ll Learn

How data engineering powers daily decision-making at a scaling tech-driven company

How to design for both humans and machines, building tools others rely on

How real-world product cycles work: from ideation to deployment (and iteration!)

How to communicate technical outcomes across teams

This is a learn-by-doing experience - mentorship included.You Might Be a Fit If You’re:

Currently pursuing a Bachelor’s in Computer Science, Data Science, Engineering, or a related field (Students on a quarter system is ideal)

Curious, analytical, and driven to understand “why,” not just “how”

Passionate about making tools that improve people’s workflows

Comfortable coding in Python (even better if you've played with APIs or data manipulation libraries)

Bonus points if you’ve ever built your own side project or explored automation just for fun

This is more than an internship. It’s your chance to build something real and get paid to learn how.
